1991 GMC S15 Jimmy 4x4 V6 4.3L
Running great still, went on a 500 mile trip last week w/no problems.
Anyway, there is one thing that is bugging me... the gas gauge on that
truck has always been off by a quarter of a tank. When I'm full, it
stays full for a looong time, and when it gets to a little under a
quarter of a tank, I'm out of fuel.
Is there an easy way to adjust the scale of that gauge electrically, or
am I stuck pulling the sensor off of the tank...?
GM has a update for the PCM on some models ..With erratic reading fuel
gauges...Seems they put two different size tanks in some models but Ran
the same program in the pcm....Call the dealer with your vin to see if
your truck is one with the update...
